One Person and One Cat Rule the World

This orange cat is called Huangdou. I took it back to my hometown in the countryside during a vacation. It ran away without noticing. When I found it, it was eating something strange growing on a tree. But the next day, the cat kept farting, like a fart-making machine that would never be exhausted. I thought Huangdou was sick, but a month later, it still farted, even if it didn't eat or drink. Finally, I realized that things were not that simple, so I decided to find a way to maximize the use of this endless fart energy.
